rtl83xx_register_switch(9)

okay so bestie, welcome to the rtl83xx_register_switch(9) page from the Kernel API Manual — this is the one that detects a switch and gets it registered, periodt 💅✨

🌸 NAME 🌸

rtl83xx_register_switch — detects a switch and registers it 🫶

✨ SYNOPSIS ✨

int rtl83xx_register_switch (struct realtek_priv *priv );

🎀 ARGUMENTS 🎀

• priv — a realtek_priv pointer. That’s the whole handoff, bestie 🫶

💖 DESCRIPTION 💖

Okay so picture this: rtl83xx_register_switch first checks the switch chip ID 👀 and then registers a DSA switch. That’s the whole glow-up: ID check first, registration after. No cap.

🦋 CONTEXT 🦋

Context check, bestie: it can sleep 😴. It also takes and releases priv->map_lock. So yeah, that lock is part of the main character energy here 🔐✨

🌈 RETURN 🌈

• 0 on success — slay ✅
• a negative value for failure — not slay, but at least you know 💀
